Formula= Vref/2^n(msb bit*2^0+nextbit*2^1+nextbit*2^2+lsb bit*2^3)
where, n= no. of bits
output= (5/2^4)(0*1+1*2+0*4+1*8)
= (5/16)(10)
= 3.125 V

A 4-bit R/2R digital-to-analog....
Here what about R/2R...?
I think 1.5625 x 2 = 3.125V
Here what about R/2R...?
I think 1.5625 x 2 = 3.125V

Vo = 5(Vi/16)
= 5(5/16)
= 1.5625
= 5(5/16)
= 1.5625
